Solved Long delay when upgrading walls

I put a wall of branches to improve its stone level but it is not immediately gets better and you need to stand and wait 20 seconds until it is improved, help fix that will immediately improve, thanks in advance!

[DOUBLEPOST=1428408224][/DOUBLEPOST]how to remove this delay, please tell me

 

If you are using an old version of CupboardExploitFix, that is likely causing the delay due to non-perfect connectivity such as packet loss or out-of-order packets. I put up a warning notice yesterday which explain there was a major flaw which could not be solved properly and that the current version of the plugin should not be used.

I released a new version a few minutes ago which attempts to solve this flaw with a workaround which worked fine during my limited testing. Please update your plugin and read the new description for the plugin so that you understand how to detect any potential issues in future.
